Very persistent caller, purporting to be from EDF, asking for our supplier meter number to match with what's on their system. Didn't give them what they asked for and asked them to email, write or visit in person. Their 'manager' refused and finalised the call be saying 'Don't blame us if you get billed wrongly'. Hopefully I wont hear back from them.

They called us to confirm our EDF energy details. Listed what they knew and simply asked us to confirm. Didn't ask for any new info. However, it did still seemed a bit odd and out of the blue. Calling EDF just now to confirm it's genuine.
